BATTERY.

SPECIFICATION forming part of Letters Patent No. 637,422, dated November21, 1899.

Y Application filed March 2, 1899. *Serial No. 707,502. (No model.)

To all whom t may concern:

Be it known that I, CHARLES B. SCHOEN- MEHL, a citizen of the UnitedStates, and a resident of Waterbury, in the county of New Haven andState of Connecticut, have invented certain new and useful Improvementsin Galvanic Batteries, of which the'followin'g is a specification.

The present invention relates to galvanic' batteries, and moreparticularly to the construction of a negative element therefor whichincludes a cover of novel construction.

It is the object of my invention to particularly improve upon theconstruction of batteries shown in my former patent, dated October 12,1897, and numbered 591,427. In this connection I particularly improveupon the construction of the top and bottom of the basket forming the'negative element of said battery by producing therein means forretaining the negative-supportsin position,and,. further, to permitquicker assemblage of the parts, as will readily be understood from thedetail description next to follow. v

With the above objects in View my invention resides and consists in thenovel construction and combination of parts shown in the accompanyingdrawings, forming a part of this specication, and upon which similarletters of 'reference denote like or corresponding parts throughout theseveral figures, and of which- Figure l shows a central verticalcross-section of my improved battery-pole, together with a similar Viewof a common form of zincv element used in connection therewith. Fig. 2is a sectional plan view showing the means for supporting the porcelainupon whichl the zinc rests. Fig. 3 shows a detail perspective view ofthe lowerportion of the basket, illustrating the pockets to receive saidporcelainsupport. Fig. 4 is a perspective view of one of saidporcelain-supports detached. Y

It will be obvious to those skilled in the art that it is not onlydesirable in the production of articles of manufacture to have themsimple in construction, but it is also a great saving of time and moneyto construct them in such a manner as to permit of quick assemblage ofthe parts. Both of the above features have been foremost in my mind inthe production of my present battery, as will be observed from thefollowing detail description.

Referring to the letters of reference marked upon the drawings, Aindicates a basket, which in practice is filled with the usualdepolarizing agent of any preferred kind. The side walls of this basketare corrugated similar in all respects to that of my former pat- 6o ent,whereby agreater operative surface is afforded, andl consequently thestrength of Athe battery enhanced. This basket is provided withdetachable top and bottom B and C,respectively,which partsare securedthereto by means of rods D D, running vertically through the basket, asshown. The tops and ,bottoms are each provided with an inwardlyextendedflange E, which in practice engages the outermost surface of thecorrugations of 7o consequently afford a particular and desirable methodfor holding said blocks, since the time consumed in attaching the sameis inconsiderable. The blocks H, of which there may be any desirednumber, are each provided with an outwardly-extended ledge I, upon whichrests the cylindrical Zinc element J, which latter is provided with theusual form of wire connection K, as will be apparent.

The top B of the basket is similar in all re- 9o spects to the bottomexcept that 'it is provided with a central opening L, through which thebasket may be charged or recharged. This opening, as will be apparent,is sufficientlyclosed by the cover M, which latter serves to inclose thejar. (Not shown.) As will be seen, the rods D, together with the nuts N,serve not only to retain the top and bottom of the basket in position,but also serve to. unite therewith the cover M, above referred roo to.Between these covers are preferably inserted insulating-washers O, andabove the top cover and between it and the nut N is also inserted asecond washer, thus securely insulating the rods, which may serve as abinding-post upon the cover and preventing the short-circniting of thebattery should the covers touch when they are connected in a series.

By reason of the two covers connected as Shown the basket may berecharged without removing the inner cover, which is particularlydesirable, since it is less trouble and expense.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. In a battery of the class described, the combination with a basket,of pockets formed against said basket and having walls upon all sides,insulating supporting-blocks retained in said pockets, and apositiveelement supported on said blocks, substantially as described. i

2. The combination in a negative electrode for batteries, of a basketcontaining a series of pockets upon its sides to receive and supportinsulating-blocks and two separate superposed detachable covers for saidbasket, the innermost one of which has a central opening therein.

3. rlhc combination in a battery-electrode of the class described, of aperforated corrugated cylindrical body, a top and bottom for said bodyand cach having inwardly-turned Hanges E forming pockets between saidflanges and said corrugations.

4. The combination in a battery-electrode of the class described, of acorrugated cylindrical body, a top and bottom for said body havinginwardlyturned anges E forming pockets between said Iianges andcorrugations, and insulating-supports retained by said pockets,substantially as shown and described.

5. In a battery of the class described, the combination with a basket,of a detachable cover having an opening therethrough, a secondary coverover said opening and adapted to inclose the battery-jar, and suitableinsulations between said covers.

6. In a battery of the class described, the combination of a corrugatedbasket, a detachable top and bottom therefor having inwardly-turnedHanges as shown, a secondary cover for said basket and the battery-jar,means for retaining said parts together, and suitable insulationsbetween the covers aforesaid.

Signed at XVaterbury, in the county of New Haven and State ofConnecticut, this 25th day of February, A. D. 1899.
